SYSTEM OF ELEC'i'R lCAL DiSTRlBUTiON.

SPECIFICATION forming part of Letters Patent No. 399,639, dated March 12, 1889. Application filed November 23, 1886. Serial No. 219,639. (No model.) Patented in England 1113' 12, 1887, No. 9,739 in Germany July 12, 1887, No. 43,129; in France July 12,1887, No. November 10, 1887, No. 27,975.

Pennsylvania, have invented certain new and useful Improvements in Systems of Electrical Distribution, (patented in England July 12, 1887, No. 9,739; in Germany July 12, 1887, No. 43,129; in France July 12,1887, No. 184,712; in

Belgium July 12, 1887, No. 78,173, and in LanadajmnmhenlihLSSLlo. ii lloiioil cnnncclmlbnthecondnc or 7 Which the following is a specification. The invention relates to the class of electric circuits employed for supplying currents from any convenient source of electricity to translating devices located at more or less distant points. I

The object of the invention is especially to provide means for supplying the required currents in such a manner that should there be any interruption in the connection of any given supply-conductor there will be convenient means at hand for substituting therefor or interchanging therewith another supplyconductor, thus providing a path for the currents until the original circuits are repaired.

The invention relates especially to the system of electrical distribution in which alternating electric currents are transmitted over main conductors to points near the stations at which they are to be utilized, at which stations electric converters are employed for transforming the currents.

In the accompanying drawing there is shown, indiagram, at system of circuits involving the features of the invention.

Referring to the figure, A represents an electric generator of any suitable-type adapted to produce in this instance alternating currents. The currents of one character are si multaneou'sly transmitted upon a series ot'in this instance threemain lines, L L L. Simultaneously currents of the opposite character are transmitted upon three other lines, L L L. These lines are adapted to carry currents of, say, two thousand volts each, and they extend near each other to points in the district where it is intended to use the cur rents for operating the incandescent lights d d cl or other suitable translating devices. The

devices are connected .in circuit with two dis- 184,742: in Belgium July 12,1887,No. 78,173, and in Canada tributing-conductors, Z Z and these conductors are supplied with other currents from the main lines through intervening converters C 0 C The primary coil p of the converter is connected in circuit bet ween mainline conductors l, and L by means of c:.mcluctors 1 and l. The converter is connected in circuit between the lines L and if in the ame manner by the conductors 2 and 5, and the primary coil 7 of the third converter, C is land w th. the

remaining pair, L and ll", of the main lines.

In this manner each converter is connected with a diiferent pair of main lines. The secondary coils 15- s s of the respective converters are connected in multiple arc with the lines I and P. The conductors L 1F, &c.-, thus combine to supply the conductors I and F. The conductors 1, 2, and 3, leading from the lines ll, L and 1), are respectively provided with switches T, T and T eaph provided with three points, t, 1 and i respectively connected with the three lines L, 1. and 1.. By this means each conductor 1, 2, and 3 may be connected with either of the three lines. The (JOlHlUCl'OlS l, 5,:1nd are likewise constructed with switches T,'.l", and T'", respect ively. These switches are each provided with contact-points f", f, and f, connected with the lines 1;, if, and 1., respectively. Upon the interruption of the connections of any line l/ L If, &c., the corresponding converter. t", C, or 0", connected therewith, could be con nected with one of the other of the conductors upon the same side of the system, and the currents required would therefore be delivered through that mainline to the converter originally connected therewith, as well as to the additionaLcon verter thus connected in circuit, the capacity of the line being such as to convey the current required more orless perfectly. in this manner if any one conductor fails the supply of the lines I F'is kept up by the other lines until the dcfcctive line is restored.

I claim as my invention 1. The combination, with a source of electricity, of multiple conductors extending from the respective poles, a series of converters having their primary coils respectively connected with different pairs of said conductors; and a 2 assess I verters having their primary coils respectively connected with different pairs of conductors thus formed, and translating devices connected in multiple are with the several second ary coils of said converters.

3. The combination, with an alternate-current electric generator, of two or more main lines extending from each pole, translating devices, (llSt llbLlfiHg-COHdUCtOIS with which said devices are connected, and means for suppiying currents to said distributing-conductore from the difierent pairs of main lines.

4. The combination of a source of alternating electric currents, a series of main lines extending from each pole thereof, a series of converters, conductors including the respective primary coils of the same, switches applied -to,onc,terminal of each of said conductors,

and contactrpoints applied to each switch con; nected with the respective main lines leading from one pole of the source.

' The combination of asource' of alternating electric currents, a series of main lines tending from one pole thereof, a series of cen- Verters, conductors leading from said main lines and including the respective primary coils of the same, switches applied to one terminal of each 01' said conductors, and contactpoints applied to each switch connected with the respective main lines and connections from the remainingterminals of said conduct ms with the remaining pole of said source.

6. The combination, with the primary coil of an electric converter, of pairs of supplyconductors, means for supplying currents of electricity thereto, and 'a circuitcontroller through which connections with the different pairs of conductors are secured.

. 7. The combination, with the primary circuit of an electric converter, of multiple mains and circuit-controlling devices for connecting any pair of said mains to said primary circuit' In testimo'n y whereof I have hereunto subscribed my name this 15th day of. November, A. l). 1880.
